menu "Init Utilities"
config INIT
bool "init"
default n
select FEATURE_SYSLOG
help
init is the first program run when the system boots.
config DEBUG_INIT
bool "debugging aid"
default n
depends on INIT
help
Turn this on to disable all the dangerous
rebooting stuff when debugging.
config FEATURE_USE_INITTAB
bool "Support reading an inittab file"
default y
depends on INIT
help
Allow init to read an inittab file when the system boot.
config FEATURE_KILL_REMOVED
bool "Support killing processes that have been removed from inittab"
default y
depends on FEATURE_USE_INITTAB
help
When respawn entries are removed from inittab and a SIGHUP is
sent to init, this feature will kill the processes that have
been removed.
config FEATURE_KILL_DELAY
int "How long to wait between TERM and KILL (0 - send TERM only)" if FEATURE_KILL_REMOVED
range 0 1024
default 0
help
With nonzero setting, init sends TERM, forks, child waits N
seconds, sends KILL and exits. Setting it too high is unwise
(child will hang around for too long and can actually kill
wrong process!)
config FEATURE_INIT_SCTTY
bool "Support running commands with a controlling-tty"
default n
depends on INIT
help
If this option is enabled a command starting with hyphen (-)
is run in its own session (setsid(2)) and possibly with a
controlling tty (TIOCSCTTY). This is not the traditional init
behavour, but is often what you want in an embedded system where
the console is only accessed during development or for maintenance.
NB: using cttyhack applet may work better.
config FEATURE_INIT_SYSLOG
bool "Enable init to write to syslog"
default n
depends on INIT
config FEATURE_EXTRA_QUIET
bool "Be _extra_ quiet on boot"
default y
depends on INIT
help
Prevent init from logging some messages to the console during boot.
config FEATURE_INIT_COREDUMPS
bool "Support dumping core for child processes (debugging only)"
default n
depends on INIT
help
If this option is enabled and the file /.init_enable_core
exists, then init will call setrlimit() to allow unlimited
core file sizes. If this option is disabled, processes
will not generate any core files.
config FEATURE_INITRD
bool "Support running init from within an initrd (not initramfs)"
default y
depends on INIT
help
Legacy support for running init under the old-style initrd. Allows
the name linuxrc to act as init, and it doesn't assume init is PID 1.
This does not apply to initramfs, which runs /init as PID 1 and
requires no special support.
config HALT
bool "poweroff, halt, and reboot"
default y
help
Stop all processes and either halt, reboot, or power off the system.
config MESG
bool "mesg"
default y
help
Mesg controls access to your terminal by others. It is typically
used to allow or disallow other users to write to your terminal
endmenu
